CCS/DRV8312-69M-KIT: generating trapezoidal by DRV8312 in 3 Phase motor driver with 6-PWM Mode

Farouk A

Part Number:

Tool/software: Code Composer Studio

the default InstaSpin project inside MotorWare was originally developed for driving the DRV8312 using the 3-PWM mode (not 6-PWM),

•• Can DRV8312 generate OUTA,OUTB, and OUTC like this picture as datasheet?

and what the CC project for that to build on the KIT DRV8312-69M-KIT, in other word

I need the code to compile on CC to generate trapezoidal signal like below

or the following if 100% internal PWM

You might download the controlSUITE as the following link
www.ti.com/.../controlsuite

And then refer to one of these two projects in the below folder, that can implement the trapezoidal control as you want.
C:\ti\controlSUITE\development_kits\DRV8312-C2-KIT_v128\BLDC_Sensorless
C:\ti\controlSUITE\development_kits\DRV8312-C2-KIT_v128\InstaSPIN_BLDC

You need to change some memory assignment for IQmath in the .cmd file as below if you are using F28069M controlCard.

FPUTABLES : origin = 0x3FD590, length = 0x0006A0 /* FPU Tables in Boot ROM */
IQTABLES : origin = 0x3FDC30, length = 0x000B50 /* IQ Math Tables in Boot ROM */
IQTABLES2 : origin = 0x3FE780, length = 0x00008C /* IQ Math Tables in Boot ROM */
IQTABLES3 : origin = 0x3FE80C, length = 0x0000AA /* IQ Math Tables in Boot ROM */

Hi, Yanming Luo,
above screenshot by Hossam for error in compiling after changing in .cmd file as recomended

Please check if the project used multi .cmd files, only need to use one except for the header file .cmd. Or post the whole .cmd file if have questions again.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
